is identical in all, and our specimen appears to more satisfactorily represent the 

 species than do the two specimens from the Amboy clays (loc. cit.) so referred by 

 Newberry, the identity of which is open to question.

Paliurus affinis Heer. ? 



PL XXXIV, figs. 6, 7. 



Paliurus affinis Heer, Fl. Foss. Arct., vol. 7, 1883, p. 42, pi. 62, figs. 16-19; Hollick, Trans. New York Acad. 

 Sci., vol. 12, 1892, p. 35, pi. 2, figs. 12, 14, 18; pL 3, fig. 7. 



It is quite possible that these specimens may belong with Paliurus cretaceus 

 Lesq., a which is so closely similar in appearance to P. affinis Heer, as to be hardly 

 distinguishable from it, but they are too fragmentary for satisfactory comparison.

This beautiful little species is represented in our collections from Glen Cove by 

 a number of fragments as well as by the perfect type specimen, the figure of which 

 is here reproduced. It occurs with and is evidently closely related to the species 

 next described. 



Locality: Glen Cove, Long Island. Collected by Arthur Hollick. Specimen 

 in Mus. New York Bot. Gard. 



ZizYPHtrs oblongtjs n. sp. 

 PI. XXXIV, figs. 9, 10. 



Zizyphus elegans Hollick in part, Bull. Torrey Bot. Club, vol. 21, 1894, p. 58, pi. 177, fig. 10; Bull. New 



York Bot. Gard., vol. 3, 1904, p. 415, pi. 73, fig. 4. 



Leaves oblong, entire, 3-nerved from the base; lateral primaries rather sharply curved below, soon extend- 

 ing upward subparallel with the midrib, giving off branches on the outside, the latter forming acute angles 

 with the lateral primaries, and curving upward toward the margins; midrib and lateral primaries connected 

 by an irregularly disposed system of fine cross nervation. 



This species was originally included by me in Zizyphus elegans (loc. cit.), but 

 this was due to the imperfect specimen, the illustration of which is reproduced in 

 fig. 9. New material since obtained indicates that a distinct species should be 

 recognized, characterized by an oblong instead of ovate form of leaf. Thus far I 

 have not succeeded in finding any specimen which shows the upper part, so that it 

 is impossible to determine whether the oblong character of the lower part prevails 

 throughout.
